汽車(chē)發(fā)動(dòng)機(jī)凸輪軸加工工藝及兩套專(zhuān)用夾具設(shè)計(jì)【全套含CAD圖紙】,全套含CAD圖紙,汽車(chē)發(fā)動(dòng)機(jī),凸輪軸,加工,工藝,專(zhuān)用,夾具,設(shè)計(jì),全套,cad,圖紙 摘 要 我的畢業(yè)設(shè)計(jì)課題是凸輪軸的工藝工裝，凸輪軸對(duì)其工作要求、部分精度較高，如軸上的油孔的加工、法蘭盤(pán)孔的加工等。凸輪軸的工藝過(guò)程，我們盡量做到清晰明了，在保證表達(dá)清楚的基礎(chǔ)上，盡量做到簡(jiǎn)練。在此設(shè)計(jì)中，鞏固了機(jī)械制造專(zhuān)業(yè)的專(zhuān)業(yè)知識(shí)，學(xué)習(xí)機(jī)械加工工藝、夾具設(shè)計(jì)、金屬切削原理與刀具及金屬切削機(jī)床。在此，我們?cè)O(shè)計(jì)了兩套鉆床夾具，并進(jìn)行了一些機(jī)構(gòu)的設(shè)計(jì)，如分度機(jī)構(gòu)、頂尖機(jī)構(gòu)、液壓傳動(dòng)機(jī)構(gòu)等，還借用了機(jī)床尾座、手輪等大量通用件，既有利于加工，又節(jié)省不少力氣。其中，夾具設(shè)計(jì)需要保證被加工面的位置精度；減少輔助時(shí)間，提高勞動(dòng)生產(chǎn)慮；擴(kuò)大機(jī)床的使用范圍；實(shí)現(xiàn)工件的裝夾加工并減輕勞動(dòng)強(qiáng)度，改善工作條件，保證了生產(chǎn)安全。此次設(shè)計(jì)，由于我的水平有限，難免會(huì)出現(xiàn)錯(cuò)誤，望讀者進(jìn)行批評(píng)指正。 關(guān)鍵詞：凸輪軸；鉆床夾具；分度機(jī)構(gòu)；液壓傳動(dòng)機(jī)構(gòu) Abstract My graduation project subject is a craft frock of the camshaft, the camshaft is by their job requirements. To the precision being relatively high, for instance, oil processing of hole of axle. Processing of the hole of the ring flange, etc., the course of the camshaft, we try our best to accomplish clearly, on the ground of guaranteeing to express clearly. Try one’s best to accomplish as perfect as crystal. In the course of design, consolidate our knowledge about mechanism manufacturing, and I have grasped mechanic craft, tongs design, the principle of metal cutting tools and the metals cutting the machine tools. In this design, we have designed two sets of drilling machines digs. In the design, I have designed some sets of mechanisms. Such as, graduation organization, top structure, hydraulic transmission mechanism and so on. I take advantage of lathe tail flat also, as large amount of common parts, such as handwheel favorable to process and so on. Save much strength. Among them, the tongs design demand guarantee which is processed the position accuracy; Reduce to lend support the time and increasements labor produce, extend the usage scope of the machine tools. Realize the work piece pack to clip to process to combine alleviative labor strength, improve the work term and guarantee the production safety. This design, because we have limited level. Unavoidable to appear some mistakes, so I hope that readers can make some re-comments.
